Two things that never meet or pass are called parallel objects. Or parallel lines.
Yes, a precipitate is a physical change. It occurs when two solutions react to form a solid that settles out of the solution. This is a reversible change as the solid can be redissolved back into the solution.
Wood. A lot of things can be a solid. Think of solid not as much as an object but a state. For example water can be either gaseous (vapour), liquid (condensation) or solid (ice).
What two thing's change a sedimentary rock into a metamorphic rock
Hair and nails are the two things on a human that never stop growing, although they do eventually reach a point where they stop growing longer.
It's when the anwser varies from things to things
Two things that never meet or pass are called parallel objects. Or parallel lines.
The mass of the two chemicals are just combined, and are never changed. They may change forms, like from a solid to a gas, but the mass is always the same.
Yes, if it occurs as the result of a chemical reaction. For example, if two clear colorless solutions form a white precipitate (solid) when mixed, that would be an example of a chemical change. The formation of a solid from freezing is a physical change.

Please note that a "change of state" involves TWO states, not just one. Using just the three most common states of matter: * A solid can change to a gas * A liquid can change to a gas * A gas can change to a liquid * A gas can change to a solid * A solid can change to a liquid * A liquid can change to a solid The first four changes in the list above involve gases.

A solid has two main forms. Amorphous is where the molecules aren't in a perfect pattern, allowing change to the structure. Crystalline is where the molecules are in a perfect pattern, disallowing change.

Landlines did not change to mobiles. They are two different things.
